Description

The method for creation of effective heat transfer surfaces for one-phase flows, boiling, condensation, and radiation are considered. The results of experimental and analytical studies of the laws governing enhancement of heat transfer processes and influence of a macro- and microstructure of surfaces on the mechanism and characteristics of heat transfer are systematized. The concept of a real phase interface – a transition surface region – is introduced. The methods of enhancement of heat transfer in different channels of heat exchanging apparatuses are considered. Practical recommendations for a choice of ways of heat transfer enhancement, calculations of heat transfer, and hydraulic losses are given.
